Latest Patents
Mark N Sun's latest patents include innovative solutions for reducing reverse currents in synchronous rectifier circuits. His first patent addresses the issue of reverse currents that can damage circuits or limit their efficiency. By utilizing an auxiliary winding, the design allows an output inductor to drive the secondary side rectifiers, effectively limiting their conduction time as reverse currents increase. This approach ensures that negative currents are self-adjusted to a minimal percentage of load current, preventing issues when operating in parallel with other modules.
The second patent, a clamping circuit and method for synchronous rectification, introduces a rectifier circuit equipped with voltage clamping circuitry. This design features a transformer with primary and secondary windings, along with transistor switches connected to the secondary winding. The circuit includes diodes that absorb energy from voltage spikes and high-frequency ringing, effectively recycling this energy to control the operation of the transistor switches.
